用be动词的正确形式填空

Answer 1

be动词的意思be动词意思和用法很多，一般的意思是：是，此种用法，有多种变化形式，is，am，are，was，were，being，been，to be.另外，be动词还有成为的意思。根据句子中不同的人称、数和时态，应该选择相应的be动词。要看句语的时态:如果是一般过去时,就用was/were如果是一般现在时,就用am/is/are如果是一般将来时,就用will be然后看主语的人称及复数形式:一般过去时：第一人称和第三人称的单数形式，则用was第一人称和第二人称、第三人称的复数，则用were一般现在时：第一人称单数形式，用am第三人称单数形式，用is第一人称和第二人称、第三人称的复数形式，则用are一般将来时：will be口诀：一般时态有关be动词的口诀我用am，你用are，is连接他/她/它，复数形式就用are编辑本段be动词的用法be （be/is/are/am/was/were)[bi:] vi 现在时 I am, you are, he is, we are, you are, they are （缩略式 I'm, you're, he's, we're, you're, they're）, （否定缩略式 I'm not, isn't, aren't）, 过去时 I was, you were, he was, we were, you were, they were （过去时否定缩略式 wasn't, weren't）, 过去分词been, 现在分词being英语的“be”是个特殊动词；有些语言，如马来文等，并没有“be”这样的动词。 “Be”除了原形的“be”之外，还有另外七种形式：am, is, are, been, being, was, were. 在句子中，“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb)编辑本段例句对照【当主动词时，“be”在性质上属于接系动词(The Linking Verb), 后面要有名词、形容词、地方副词或短语作补足语(The Complement)。】例如： 1. The man is a science teacher. 这个男子是一位科学教师 2. Mary's new dresses are colourful. 玛丽的新衣服色彩鲜艳 3. I have been there before. 我以前去过那里 4. My mother is in the kitchen now.母亲现在在厨房　【这四个都是陈述句，可以变成疑问句，方法简单，把主语和“be”或助动词对换位置即可： 5. Is the man a science teacher? 6. Are Mary's new dresses colourful? 7. Have I been there before? 8. Is mother in the kitchen now? 【当“be”要在祈使句中出现时，它必须借助 助动词“do”或“don't”之助，如： 9. Don't be silly! 10. Do be obedient! 11. Don't be a fool! 【“Be”有两种缩写法，如下： 12. He's not...../He isn't.... 13. You're not...../You aren't... 【但“am + not”的缩写法只有一个： 14. I'm not. 有人用“ain't”, 但这并不是标准英语。 谈过了“be”作主动词的功能，现在看看“be”作助动词时，有些什么用法： 【1.】“Be + 现在分词”以组成进行式时态(Continuous Tenses)，如： 15. Tony's maid is washing his new car. 16. The children are playing in the field. 17. Samuel was eating when I came in. 18. We have been living here since 1959. 【2.】“事/物人 +Be + 过去分词”以组成被动语态(The Passive Voice),如：19. Her money in the drawer was stolen20. A number of good jobs are taken up by foreigners21. David studied in Taiwan but has been trained as a language lecturer in America22. Can all the wonderful birds be found in our Bird Park23. The disobedient boy was told to stand out- side the classroom24. Steps are being taken to reduce traffic con- gestion during peak hours25. Dishonest students will be immediately dealt with

Answer 2

单数用is，复数用are，am用在I之后。

我希望你能给具体的例子，具体问题具体分析，毕竟be动词有时候是会受到时态的影响
